--------------------------------
Summary: Possible failure of TestHMasterRPCException
Key: HBASE-13040
URL: https://issues.apache.org/jira/browse/HBASE-13040
Project: HBase
Issue Type: Bug
Components: test
Reporter: zhangduo
Assignee: zhangduo
When addressing HBASE-13011, TestHMasterRPCException failed twice in PreCommit Build.
I found that the test itself has a problem. We start a HMaster, and then we continue calling
isMasterRunning and expected a ServerNotRunningYetException.
But it is possible that when we connect to HMaster, it has already finished initialization,
and we just get a 'true' response instead of an Exception.(Just add a 'Thread.sleep(1000);'
after 'HMaster hm = new HMaster(conf, cp);', you can get a stable failure).
